My screen is frozen and I cant shut down, how do I solve this?

My windows HTC One M8 has completely frozen, I can hear when someone calls or texts me but i can not interact with the screen it is currently 9:42pm est and my screen has been frozen since 9:02pm. Is there any shut down or anything I can do to solve this? All the normal resets do not work since the screen refuses to work. Any suggestions?

My phone just encounter this problem. Its frozen at the lockscreen and nothing can unlock or unfreeze it. I tried Power and Volume and still failed. I called HTC, and they asked me to wait until the battery runs out and check again. This is seriously frustrating. I had to deal with overheating issue before, and now the replacement phone has this frozen screen problem that can't be reset? Seriously???

Mine did it tonight; power and volume down at the same time! On my device I have a SanDisk Class 10 64GB micro SD card and it's a finicky card and often won't play nice when formatted and in fact the only way I've been able to format the card is via my M8W; my laptop can't do it no matter what app I use to make the attempt. So double check your microSD if you're using one. I make it a rule to do a hard reset just to make sure after an update, everything is okay. Take care!

What is being suggested is more commonly referred to as a "soft reset", a hard reset is when you can get into the phone and you choose to do a full (hard) reset which wipes the device. But the description of a hard reset in this instance is quite accurate too in many ways, it's just not referred to it that way generally. I only point this out in case you ask for help later and are confused if someone says a soft or hard reset is in order.
